Fd = Cd/Ct
this is “critical flow” or “design flow”
Choose your path carefully, or you may fall flat on your face (or worse)
“A complete data set allows for more complete understanding of the environmental fate and transport processes and may result in a more accurate permit limit because of reduced variability and uncertainties.” EPA guidance
This means that you have 10-20 different translators- how do you decide which one to use for determining permit limits???
But what if the translators are not log-normal????
But what if the translators are TSS-dependent?
The combination of these problems amounts to using the 95th percentile as a default, when other values may be equally defensible (regression equation, transformed geometric mean).
These changes will determine translators that more accurately represent the stream!
